Securing Debian Manual: 3.1 Choose a BIOS password

[Stayvoid <stayvoid@gmail.com>]

Hello.

"Before you install any operating system on your computer, set up a
BIOS password. After installation (once you have enabled bootup from
the hard disk) you should go back to the BIOS and change the boot
sequence to disable booting from floppy, CD-ROM and other devices that
shouldn't boot. Otherwise a cracker only needs physical access and a
boot disk to access your entire system." [1]
Is there a way to prevent such actions while using a VPS?

I won't have a physical access to the machine.
Is there a need to set a BIOS password for a VPS? (I've never used a
VPS, but someone told me that it's possible for some of them.) I've
been told that it's not necessary because if someone reboot the
machine I'll have no chance to enter the password.
